摘　　要：介绍了基于SRP的IB-SAN的整体结构,分析了SCSI read/write命令处理过程中的两个关键问题,即数据缓冲区的内存注册/注销方法和RDMA操作的执行者获取对方数据缓冲区信息的方式。实验结果表明,SRP能够使InfiniBand网络性能得到充分发挥,系统的总体I/O性能明显优于基于iSCSI协议的IB-SAN。The architecture of a SRP-based IB-SAN was introduced and two issues in processing a SCSI command were discussed, including the memory registration and deregistration of data buffers and the way in which memory descriptors at an initiator were sent to a target. Experimental results show that the SRP-hased IB-SAN gives out much better I/O performance than iSCSI-hased IB-SAN.
